RULES

• BLACK and WHITE each move one of their own pieces on their turn.
• You are BLACK. The computer is WHITE. BLACK moves first.
• All pieces move diagonally by one square per turn.
• A piece cannot move into a square blocked by another piece.
• Jumping over pieces is not allowed — this is NOT checkers.
• BLACK can move both left and right, i.e., can retreat.
• WHITE can only move to the right — retreat is not allowed.
• If the BLACK piece reaches the leftmost edge, BLACK wins.
• If the BLACK piece is blocked by WHITE pieces and the wall and cannot move, WHITE wins.
• Neither player may pass; a move is mandatory on each turn.
• If WHITE has no available move, the turn goes back to BLACK.

TL;DR - MOVE THE BLACK PIECE TO THE LEFTMOST EDGE.
